Biography
Simeon II of Bulgaria was born on 16 June 1937 in Sofia in the Kingdom of Bulgaria to Tsar Boris III of Bulgaria and Giovanna of Italy. He was of Bulgarian, German, Montenegrin, and Italian descent. Simeon succeeded to the throne of Bulgaria when his father died on 28 August 1943 after returning from a meeting with Adolf Hitler of allied Nazi Germany during World War II, and because Simeon was only 6, Prince Kiril of Bulgaria became the regent of the kingdom. On 5 September 1944, the Soviet Union declared war on Bulgaria and invaded the country on 8 September, deposing Kiril and the government a day later and allowing Simeon to become king. After the war's end in 1945, Simeon was forced to step down to the communists in 1946, only nine years old while king. However, Simeon became the Prime Minister in 2001 and remained in that office until the end of his term in 2005.
